Obviously we arrived too late for decent shaded pits
TR6 was running road tyres -my 195/55 R spec were worn out - possibly the only car that wasn't using R spec - acquitted itself OK but late braking was tricky with relative lack of grip and the gearing was a bit tall with a 3.45 diff. It would seem a proper R spec tyres is worth about 4 or 5 secs at Barbagallo - 195/65 Blue earth Yokohamas did bloody well considering they were $400 for 4 rather than $400 each.
Next plan is 205/60 A048 and a 3.7 LSD
